It used to be that agriculture was most of our economies. These days it's a relatively small part of the economy. The good news with that is that the burden of making sure the entire planet is well fed is not that high anymore. In the west, the food we throw away could easily feed the rest of the planet. A couple of trillionaires could probably fund most of it. People like Bill Gates actually have done quite a bit on this front, which whatever else you think of the man is quite admirable. However, just giving people money or food isn't a long term solution. Empowering people to earn a living and grow or buy food is a much more structural fix. Mostly it boils down to ending local conflicts and wars. In the eighties, Live Aid was a big campaign against hunger in places like Ethiopia. It's doing somewhat better these days. But it still has a lot of conflict. But, it also has economic growth and that has slowly been pulling people out of poverty there. Another fix is restoring land. There's a big project to stop the Sahara from expanding further south that involves a green wall. It's a successful project where people dig simple U shaped trenches to capture rain water. Instead of flooding away with top soil, the water now stays and turns land back into usable farm land. This project has been running for a few years. The local population seems to get it and is now enthusiastically implementing it all over the place. They can grow food, sell it on local markets, and graze their live stock. The Sahel is also a region where poverty has fueled a lot of conflict over land and resources. So, it's a double success in the sens that it takes away some of the root causes for that kind of conflict.
